I've been testing out Nagios in general to replace our current system and I noticed a strange blank in my PNP graphs this morning. When I looked closer, I found that nagios had basically hung for several hours. Then, the log shows a warning of:
[1246958195] Warning: A system time change of 0d 4h 56m 48s (forwards in time) has been detected. Compensating... and then for several hours, messages like: [1246958830] Warning: The check of host 'superhost1' looks like it was orphaned (results never came back). I'm scheduling an immediate check of the host... I'm running nagios 3.0.6 with ndo2db. The system has under 1000 services, most of which are nrpe checks to remote hosts. The nagios system was not terribly loaded at the time (about 50% idle) and mysql did not show any errors at the time. Typically, the number of buffers used is only 2-3 out of the 4096. Any ideas as to what this could have been, or how I can detect this condition or log to gain more info? I wouldn't think that this is normal, but my Google searches aren't turning up a lot.
